Need polarizer foil info for Game & Watch repair...

I have a Game & Watch with a burnt polarizer.

Tried replacing the foil with the polarizer from an old monitor. Works like a charm, but the foil has a matte finish. And the tint is not completely the same either...

Any idea where I can find replacement polarizers for it, and what specs they should have?...

 

Well, I did find this:

So I guess I'll try my luck there then...
